Finding the underserved: directions for HIV care in the future.

Area of Science:

• Public Health
• Health Services Research
• Epidemiology

Background:

• The HIV epidemic disproportionately affects vulnerable populations.
• Traditional healthcare systems may underrepresent individuals with complex social and behavioral needs.
• Demonstration projects aim to improve access to HIV medical and psychosocial support services for underserved groups.

Purpose of the Study:

• To assess the demographic, behavioral, and background characteristics of participants in national HIV demonstration projects.
• To identify individuals with high service needs and potential underrepresentation in the healthcare system.
• To evaluate whether these projects successfully attracted and served their target populations.

Main Methods:

• Analysis of data from 4,804 participants across 17 national demonstration projects.
• Development of a "service need" index based on 15 coded characteristics.
• Utilizing CHAID (Chi-squared Automatic Interaction Detection) modeling to identify vulnerable groups.

Main Results:

• The majority of participants (87.7%) exhibited four or more "service need" factors.
• CHAID modeling identified specific subgroups with the highest levels of service need and vulnerability.
• The projects effectively recruited and served individuals with significant barriers to traditional healthcare access.

Conclusions:

• National HIV demonstration projects successfully reached and served populations with high service needs, including those often underrepresented in healthcare.
• The findings highlight the importance of tailored service delivery models for addressing the evolving demographics of the HIV epidemic.
• These projects demonstrate a successful strategy for improving health equity in HIV care.
